    This is the 3rd SSA meter I have purchased. I sold one to a friend because I bought a spare. Then stupid me lost my spare at a car audio show so I had to order a 3rd one. Enough said.

    SSA APM-X SPL Meter

    Posted by Jeremy Williams on 24th May 2022

    Absolutely LOVE this SPL meter. After purchasing the meter, I sold my Termlab Magnum. The APM-X is MUCH easier to use. It also has the awesome video feature which shows the SPL scores on screen. No wires to connect to another device. It also is rechargeable just like any other cell phone, tablet, etc via USB cable. I liked it so much, I actually bought a second unit. Definitely worth the price for the convenience over the Termlab.
